This class will cover the first topic in AQA A level biology, which is biological molecules. This will include: carbohydrates, lipids, proteins, enzymes, DNA and ATP, water and inorganic ions. Not only do I aim to make this class interactive by using online quizzes and online wordwall activities, we will also go through some exam questions towards the end. Students will have access to resources used in the lesson, and relevant exam question packs. This class is designed to give students starting in year 12 a little more support in one of the first topics which will be taught in A level biology.
In this first session we will introduce biological molecules by looking at monomers and polymers, specifically those for carbohydrates. We will look into the different monosaccharides, disaccharides and polysaccharides – looking at how the structure relates to the function for various examples. We will also cover lipids in this lesson.
In this lesson we will look through the 4 structural levels of proteins, alongside the two main types of protein (fibrous and globular). Following this we will look into enzymes in a little more detail, including the structure and function and the required practical.
In this lesson we will be going through the structure of DNA – the vital molecule for life. We will also look at how this compares to the structure of RNA. We will then look through the semi-conservative replication of DNA.
In this last session together we will be going through the smaller topics in this unit, which include ATP, water and inorganic ions. Following this we will be reviewing a mixture of past paper exam questions on the biological molecules topic.
I am just a genuine, non-judgemental person who wants to help others to understand, learn and succeed in their studies.
